I've had several bfp's this past week, with ep@home pregnancy, first response, and clear blue. I took 2 last night both saying pregnant or with 2 visible lines. The doctor was able to get me in today and I did a urine test around 11? It came back negative! She said she tested same sample again and came back with faint line. So I got bloodwork done and it's at 66 HCG. My period is actually due tomorrow- I'm around 4 weeks 1-3 days. Doctor told me to be "apprehensive more than hopeful." I actually miscarried in January so would be so happy if I was pregnant. She seemed to think 66 was low for where I'm at and given that it didn't show with their urine sample. When I got bloodwork done last pregnancy at 5 1/2 weeks my HCG was 223 and they thought that was normal...

Also, I tested again when I got home from work with HPT and came back with solid line on my cheapy test. Two questions, 1) why wouldn't it show up on theirs (especially when it's coming up on 3 different brands for me) and 2) is HCG actually low? I'm re-testing Saturday.

Some dr's offices use tests that aren't very sensitive. It's very common actually. You'd think they'd get with the times and get the more sensitive ones since they're so cheap now. Sounds like you're perfectly fine!

They would get a negative reading if they dipped it in the urine and looked at it right away. When your hcg is low it can take longer to get a positive. That's probably why they got a positive the second time. 66 isn't bad for 4 weeks. I'd try and get a second test and see if it's doubling.

They're making me test tomorrow (48 hours after). Fingers crossed and prayers! I did test again tonight like a crazy person. And this morning. This morning it was a little fainter but tonight it's definitely darker than weds original solid line. Hoping all these things are good signs!

I think the fact that the lines are getting darker means its going up! I had a faint BFP on a FRER the day before (it detects hcg at 25), so the next day i had my beta at 47 (at 3w5) which to me it made sense as it was "double" from a faint 25 test.., but my obgyn friend told me it was low also.. i got a soooo dissapointed, so I looked around on the internet and found this site that restored my hope:

The freR actually can detect an hcg level of 6! I know this from past chemicals and having my blood tests so often. But it's hard to use for guessing hcg levels as it depends how much liquid intake you have in you system at the time you pee on a stick.

Got the call from the doctor- my HCG levels are 231 now from 66 (Thurs to Sat)! She said all looks good and I'll have an early ultrasound in 2 weeks to check on things! Thanks for all the positive comments and support! Hoping this pregnancy sticks and wishing everyone else a happy, healthy pregnancy! :)
